An 18 year old from a village in Nepal outdoes US companies spending millions on R&D. Too much ‘out of the box’ thinking for us nowadays, I guess. An example of why we have dropped to #2 in competitiveness? At least we have this.

A new type of solar panel using human hair could provide the world with cheap, green electricity, believes its teenage inventor.

Milan Karki, 18, who comes from a village in rural Nepal, believes he has found the solution to the developing world’s energy needs.

The young inventor says hair is easy to use as a conductor in solar panels and could revolutionise renewable energy.
The solar panel, which produces 9 V (18 W) of energy, costs around £23 to make from raw materials. But if they were mass-produced, Milan says they could be sold for less than half that price, which could make them a quarter of the price of those already on the market.

Melanin, a pigment that gives hair its colour, is light sensitive and also acts as a type of conductor. Because hair is far cheaper than silicon the appliance is less costly.

    Now we know how best to employ the obnoxious (redundant) Guidos that have been making our sinks look disgusting for centuries.

    We’ll never hear another word about this, just like hundreds of stories from the old “Popular Science” and “Popular Mechanix,” both of which regularly carried stories about the promising progress on flying cars, etc.

    This is incredible, that’s enough power to run transistor radios for 6 billion homes, that is, if you cover the entire earth with hair.

  5. I like this data presented and it has given me some sort of desire to have success for some reason, so thanks.
